The correct answer would be 4 5/8.
Answer:
Step-by-step explanation:A car takes 4 hours to reach a destination travelling at the speed of 63 km/h.
Speed = distance / time
Distance = speed × time
Distance it took the car, travelling for 4 hours to a destination at a speed of 63 kilometers per hour would be
4 × 63 = 252 kilometers.
if the car travels at a different speed of 56 kilometers per hour and the distance remains 252 kilometers, the time it takes will be
Time = distance / speed
= 252/56 = 4.5 hours
The time varies inversely with the speed. The more the speed, the lesser the time and the lesser the speed, the more the time.
Let speed = s and let time = t
s varies inversely with t
Introducing constant of inverse variation k, it becomes
s = k/t
When s = 56, t = 4.5
56 = k/4.5
k = 4.5 × 56 =252
This is the distance

Answer:
The new perimeter is 4.6 times the original perimeter of the parallelogram.
Step-by-step explanation:
A parallelogram is a four-sided figure, such that the opposite sides are parallel.
So a parallelogram is defined by two measures, we can define them as the length L and the width W (W can be equal to L, as in the case of the square or the rhombus)
The perimeter of one parallelogram is then:
P = 2*L + 2*W = 2*(L + W)
If a scale factor of 4.6 is applied to the parallelogram, then all the dimensions must be multiplied by 4.6
This means that the new length is L' = 4.6*L and the new width is W' = 4.6*W
Then the new perimeter is:
P' = 2*W' + 2*L' = 2*(L' + W') = 2*(4.6*L + 4.6*W) = 4.6*[2*(L + W)]
And the thing inside brackets is equal to the original perimeter, then:
P' = 4.6*P
The new perimeter is 4.6 times the original perimeter of the parallelogram.
